We present a patient with essential tremor who spontaneously improved after a sensorimotor stroke related to a small cortical infarct near by the left precentral region of the brain. This finding supports the presence of cortical or transcortical motor loops that are likely involved in essential tremor and suggests a possible link with the cerebellar–thalamic–cortical pathway. © 2006 Movement Disorder Society
